Question

Anyone could walk me through , to set up the equation:

A flat rectangular piece of aluminum has a perimeter of 62 inches. The lenght is 9 inches longer than the width. Find the width.

Answer 1

@518nad

Answer 2

perimeter = 2L+2W
L=9+W

62=2(9+W)+2W
62=18+2W+2W
62-18=4W
W=11

Answer 3

omg you are really fast!

Answer 4

it doesnt matter how fast I do it, do you understand?

Answer 5

for sure

Answer 6

okay do another question for me
50 is perimeter Length is 2 times width, what is Length?

Answer 7

perimeter = 2w + 2l
l =2w or 2 +w ?

Answer 8

2+w means 2 more than width
2W = w+w , thats 2 times width

Answer 9

anyway: 50 =2w + 2(2w)

Answer 10

right ?

Answer 11

w = 25 /3

Answer 12

but i asked for length

Answer 13

oh sorry

Answer 14

you must read question more carefully, if this was a test, your teacher cant give you any marks for that

Answer 15

even though you did all that work

Answer 17

ok bro
let me see if solved this one right

Answer 18

okay so what is Length

Answer 19

use L=2W

Answer 20

l=25

Answer 21

w=25/3

Answer 22

L=2w
=2*(25/3)
=?

Answer 23

nah
